Expand description

When true, the next WM_SETFOCUS delivered to a subclassed pane HWND is allowed through instead of being redirected back to the parent.

The frontend’s giveFocus() -> browser_pane_focus IPC sets this flag before calling SetFocus on the pane, so user-initiated focus works even though Chromium’s internal focus-steal on navigation is blocked.
